I bought used heddles on ebay. While the purchased heddle length fits the harness exactly as the originals, the eyes don't match exactly. I've flipped them and they still are not exact. There is an overlap, where the eyes of the purchased and the originals match, but the purchased heddle eyes fall slightly above the originals. Will it affect my weaving? I understand about directional twist, but I wonder if I will be sorry to warp the loom only to find out I have an issue because the threads the heddles are not exactly lined up. Thanks for any input!
